Title:
CALIBRATION METHOD AND CONTROL METHOD
Document Type and Number:
Japanese Patent JP2001276214
Kind Code:
A
Abstract:
To calibrate a pump subject to changes in the flow rate attributed to changes in inlet pressure, for example, a peristaltic pump used in medical equipment.
The inlet pressure of a pump is previously measured, an average inlet pressure is derived from the measured values by using a direct or regression technique and an inlet pressure is set so as to coincide with the average inlet pressure. This calibration method is performed for the pump itself thereby making it free from the accuracy of a pressure sensor.
